It's obviously not finished, and its rolling on Gallardo wheels. It's bascily going to be a Lamborghini in Audi clothes.

(Kinda like the Audi S8 with the Gallardo motor)
"As for a little background on the vehicle - when the car debuted at its first auto shows over two years ago, it was a two-seater, mid-mounted 610 HP V-10 supercar. It's rumored that there haven't been many changes to that configuration for the production model. The Audi R8 is said to be released sometime in 2007, but no definite date has been set."
This isn't a full undisguised car yet. The black trim will all be painted for production, the red bar between the taillights is tape, and the distinctive aluminum side panel from the Le Mans concept will make production (you can see the outline of it on that car.) It will debut with the 420hp 4.2 V8 from the RS4, with the 5.2 Gallardo V10 from the S6/S8 with a little more power coming a year later.
